Benefits of technology

The patent describes a disc pump system that includes a cylindrical pump body with end walls that have driven discs on them. The system includes an actuator that causes the driven discs to move in a perpendicular motion and an isolator to reduce damping of the movement. The system also has a valve for controlling fluid flow. The technical effect of this system is higher efficiency in pumping fluid compared to other pumps.

Problems solved by technology

However, high amplitude acoustic resonance has not been employed within disc-shaped cavities in which radial pressure oscillations are excited until recently.

Abstract

A disc pump system includes a pump body having a substantially cylindrical shape defining a cavity for containing a fluid, the cavity being formed by a side wall closed at both ends by substantially circular end walls, at least one of the end walls being a driven end wall. The system includes an actuator operatively associated with the driven end wall to cause an oscillatory motion of the driven end and an isolator is operatively associated with the peripheral portion of the driven end wall to reduce damping of the displacement oscillations. The isolator comprises a flexible material, which in turn includes an RFID tag.

Description

[0001]The present invention claims the benefit, under 35 USC §119(e), of the filing of U.S. Provisional Patent Application Ser. No. 61 / 597,493, entitled “Systems and Methods for Monitoring a Disc Pump System using RFID,” filed Feb. 10, 2012, by Locke et al., which is incorporated herein by reference for all purposes.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The illustrative embodiments of the invention relate generally to a disc pump for fluid and, more specifically, to a disc pump in which the pumping cavity is substantially cylindrically shaped having end walls and a side wall between the end walls with an actuator disposed between the end walls. The illustrative embodiments of the invention relate more specifically to a disc pump having a valve mounted in the actuator and at least one additional valve mounted in one of the end walls.[0004]2. Description of Related Art[0005]The generation of high amplitude pressure oscillations in closed cavities has received...
